Embodiment

For above-mentioned purpose, the feature and advantage that make the embodiment of the invention can become apparent more, the embodiment of the invention is described in further detail below in conjunction with the drawings and specific embodiments.

The inventor is through discovering, has RemoteAddress and Subnet Mask attribute in the TFT IP filter among the existing TFT, be external network entity (external network entity) address and subnet mask, because prior art thinks that the initiator of service request is a portable terminal, the IP address of therefore giving tacit consent to portable terminal is fixing one.But the situation that connects external network for the public portable terminal of a plurality of equipment in the localized network, just the Business Stream of the uplink message that the equipment in the localized network can't be sent is tied in the suitable carrying, guarantee the QoS that this Business Stream is required, can't realize thus the uplink message that each described equipment sends is carried out PCC.The embodiment of the invention is by mating the IP address of the equipment in the localized network of source IP address attribute in the up PCC IP filter and transmission uplink message, the IP address of the equipment in the localized network of purpose IP address properties in the descending PCC IP filter and reception downlink message is mated, realized the equipment in the localized network is carried out the purpose of accurate PCC.

Embodiment one

Present embodiment provides the method for a kind of implementation strategy with the control of chargeing, and as shown in Figure 2, comprises the steps:

The uplink message that the equipment by the localized network that is arranged in described portable terminal agency that S101, mobile terminal receive transmit sends; Described uplink message is transmitted by the carrying corresponding with described TFT IP filter after matching the TFT IP filter corresponding with the IP address of equipment in the described uplink message by portable terminal.

Described uplink message is gone out the TFT IP filter and is tied in the carrying corresponding with described TFT IP filter to be transmitted to GW by the IP matching addresses of portable terminal according to described equipment.

The embodiment of the invention has increased mobile terminal side IP address of equipment attribute (certainly realizing by other attributes of expansion or newly-increased attribute) in the TFT IP filter, be used for and the IP matching addresses that sends the equipment of uplink message to portable terminal, make external network can identify this equipment in the localized network thus by the uplink message that this portable terminal is transmitted; When portable terminal was not acted on behalf of localized network, this mobile terminal side IP address of equipment attribute just was used for the IP matching addresses with portable terminal, so the scheme of the embodiment of the invention can not act on behalf of the scene of localized network well compatible with existing portable terminal.

Portable terminal in the embodiment of the invention is the agency who connects network as equipment in the localized network, and the uplink message that equipment in the localized network is sent is transmitted to GW.

Consider the problem of treatment effeciency, the quantity of IP filter is limited, therefore, and the corresponding continuous address field of the mobile terminal side IP address of equipment attribute in the TFT IP filter or certain host address.

S102, match with described uplink message in the corresponding up PCC IP filter in IP address of equipment, according to the up PCC rule of described up PCC IP filter correspondence, described uplink message is carried out strategy and charging control PCC.

Each PCC rule comprises a PCC IP filter (Packet Filter) at least, and at the qos parameter and the charging requirement of this PCC IP filter.The PCC rule is divided into up PCC rule and descending PCC rule, and the PCC IP filter basis wherein difference of attribute value is divided into up PCC IP filter and descending PCC IP filter; In the up PCC rule is up PCC IP filter, and in the descending PCC rule is descending PCC IP filter.Every the PCC rule has priority, if PCC IP filter corresponding many PCC rules, just think that unique PCC rule of limit priority of PCC IP filter correspondence comes into force.So match the PCC IP filter, promptly found corresponding PCC rule.

Present embodiment is by increasing mobile terminal side IP address of equipment attribute to the IP filter among the TFT, make portable terminal can go out the TFT IP filter and transmit, satisfy the qos requirement of distinct device by the carrying corresponding with described TFT IP filter according to the Internet protocol IP matching addresses of described equipment; Simultaneously, GW is when receiving the uplink message of portable terminal forwarding, by IP matching addresses with source IP address attribute in the up PCC IP filter and described equipment, can be according to the IP address of described equipment, described equipment is carried out accurate policy control and charging, thereby reach the purpose of a plurality of equipment of common moving terminal connection network being carried out PCC.

In the another embodiment of the present invention, can also further may further comprise the steps on the basis of embodiment one: the purpose IP address that receives the external network transmission is the downlink message of IP address of equipment in the described localized network, obtain with described downlink message in the descending strategy and the charging control PCC IP filter of IP matching addresses of equipment, according to the descending PCC rule of described descending PCC IP filter correspondence, described downlink message is carried out PCC.

Receive purpose IP address that external network sends when being the downlink message of described IP address of equipment at GW, the corresponding descending PCC rule of descending PCC IP filter that needs basis and described downlink message to mate, described downlink message is carried out PCC, for example: check some webpage or use some business if limit this equipment in the descending PCC rule of the IP address correspondence of this equipment, can forbid that then the corresponding service of this equipment uses request.

Present embodiment is compared with embodiment one, increased GW carries out PCC to the downlink message that sends to equipment in the localized network process, the downlink message that returns to described equipment by uplink message that described equipment is sent and external network carries out PCC respectively, has realized each equipment in portable terminal agency's the localized network is carried out the purpose of accurate PCC.

Embodiment two

As shown in Figure 3, the networking schematic diagram that divides into groups to insert for the common moving terminal of the embodiment of the invention.A plurality of equipment (equipment 1, equipment 2......) that portable terminal is acted on behalf of in the localized network carry out data interaction by wireless access network and GW, GW can carry out data interaction by IP backbone and external network (main office network and Internet), GW can obtain the PCC rule of equipment in the localized network from PCRF, and the PCC rule on the PCRF also can be obtained from SPR.

The implementation strategy of present embodiment and the method for chargeing and controlling as shown in Figure 4, comprise the steps:

S301, GW obtain the network segment address of described portable terminal agency's localized network.

When connection of mobile terminal into network, gateway GW can return to portable terminal to the IP address that this portable terminal itself uses, and this IP address can be the IPv4 address, or the IPv6 address prefix.

GW can obtain the network segment address of portable terminal agency's localized network with Radius (Remote Authentication Dial-In User Service, remote authentication dial-in customer service) server interaction.Described network segment address is signatory in advance predetermined by the client of tissue local network, is configured on the Radius server together with mobile terminal identification.When portable terminal connects wireless access network, after the Radius server is received the mobile terminal identification (as information such as mobile terminal user name, telephone number or IMSI numbers) of GW transmission, network segment address that can will be corresponding with this sign returns to GW together with the IP address of portable terminal use itself, and GW will be handed down to portable terminal to the IP address of portable terminal use itself.

GW also can obtain the network segment address of portable terminal agency's localized network alternately with portable terminal by dynamic routing protocol.Particularly, the network segment address of its agency's of configured in advance localized network on the portable terminal, the sign (for example IMSI) of the described portable terminal of the last configured in advance of GW and be used for directly being the local pool of portable terminal distributing IP address.When portable terminal is connected to wireless network, after the GW identification mobile terminal identification, directly from local pool, distributes the IP address of a portable terminal use itself, and return to portable terminal.GW uses another IP address with the IP address same network segment of distributing to portable terminal use itself to move dynamic routing protocol afterwards, portable terminal is the same dynamic routing protocol of IP address operation of use itself also, for example, OSPF (Open Shortest Path First, Open Shortest Path First) or RIP (Routing information Protocol, RIP).Afterwards, it is adjacent node each other that GW and portable terminal will be found respectively, and then can carry out the mutual of routing iinformation each other.

According to existing dynamic routing protocol, portable terminal is the information of the IP address of portable terminal use itself in the next hop address of the IP message of the network segment address scope of carrying the localized network that purpose IP address is positioned at its agency in the dynamic routing protocol message that GW sends, GW receives and resolves this dynamic routing protocol message, can obtain the network segment address of portable terminal agency's localized network.

Above under two kinds of situations, for the IPv4 network, described network segment address is IPv4 address field information and mask information; For the IPv6 network, described network segment address is the IPv6 address prefix information.

S302, GW obtain the up PCC rule of equipment in the described localized network from PCRF.

The PCC rule of the last management of PCRF can be the business information in the session information that provides according to AF, dynamically generates in conjunction with user signing contract information and local carrier policy, also can be that the CAMEL-Subscription-Information etc. according to the user is pre-configured.

In the PCC rule of prior art, have the attribute corresponding (the purpose IP address properties in source IP address attribute in the up PCC IP filter and the descending PCC IP filter) in the PCC IP filter with the mobile terminal IP address, but the corresponding attribute of IP address of equipment in the localized network that does not have to act on behalf of with portable terminal; Therefore, can't be suitable for the applicable cases that portable terminal is acted on behalf of localized network.

And in the PCC IP filter in the embodiment of the invention, source IP address attribute in the up PCC IP filter is used for and sends the IP address of equipment coupling of uplink message, purpose IP address properties in the descending PCC IP filter is used for and receives the IP address of equipment coupling of external network downlink message, thereby can realize the equipment in portable terminal agency's the localized network is carried out certainly realizing the purpose of accurate PCC by other attributes of expansion or newly-increased attribute.

GW obtains from PCRF that the up PCC rule of equipment can be in the described localized network, obtains the up PCC rule of equipment all in the localized network or the up PCC rule (for example some equipment does not dispose the PCC rule) of equipment component.And GW also can obtain descending PCC rule simultaneously from PCRF, so that follow-uply can carry out PCC when receiving downlink message.

The embodiment of the invention provides two kinds of described GW to obtain the mode of the up PCC rule of equipment in the localized network from PCRF:

1) GW sends to PCRF with the network segment address of described localized network; PCRF returns to described GW with the up PCC rule of described network segment address correspondence.

GW uploads for the IPv4 address of portable terminal distribution or by Framed-IPv6-Prefix to PCRF by the Framed-IP-Address in the CC-Request message and uploads the IPv6 address prefix that distributes into portable terminal in the prior art, and the response message of this order carries the PCC rule of described portable terminal.

In the embodiment of the invention, can be to (the Attribute Value Pair of the AVP in the CC-Request message, a pair of attribute and value) expand, carry the employed network segment address of a plurality of equipment that public described portable terminal divides into groups to insert by the cell of expanding.

For example, increase IPv4 address field information that Framed-Subnet-IP-Address describes the equipment that the common moving terminal divides into groups to insert, increase the IPv4 mask information that Framed-Subnet-IP-Netmask describes the equipment that the common moving terminal divides into groups to insert.Wherein Framed-Subnet-IP-Address is identical with type and the length of Framed-IP-Address, and Framed-Subnet-IP-Netmask is identical with type and the length of Framed-IP-Netmask, specifically can be with reference to the definition among the RFC4005.Equally, can increase the IPv6 address prefix information that Framed-Subnet-IPv6-Prefix describes the equipment that the common moving terminal divides into groups to insert, Framed-Subnet-IPv6-Prefix is identical with type and the length of Framed-IPv6-Prefix, specifically can be with reference to the definition among the RFC4005.

PCRF finds out the source IP address attribute up PCC IP filter corresponding with described network segment address earlier, more described up PCC IP filter is returned to GW.Perhaps, PCRF can find out source IP address attribute up PCC IP filter corresponding with described network segment address and the purpose IP address descending PCC IP filter corresponding with described network segment address simultaneously, PCC rule with described up PCC IP filter and downstream packets filter correspondence returns to GW again, comprises the PCC IP filter in the PCC rule.

2) GW sends to PCRF with the sign of the portable terminal in the described uplink message (can be telephone number or IMSI number or GW are information such as portable terminal IP address allocated one of at least); PCRF obtains the up PCC rule of equipment the localized network with the sign corresponding mobile terminal of described portable terminal agency from SPR; PCRF returns to described GW with described up PCC rule.

More excellent, GW sends to PCRF with the sign (comprising that telephone number, IMSI number and GW are the portable terminal IP address allocated) of the portable terminal in the described uplink message; PCRF obtains the up PCC rule of equipment in the localized network that telephone number, IMSI number or GW the sign with described portable terminal is the some corresponding mobile terminal agencies in the portable terminal IP address allocated from SPR; PCRF returns to described GW with described up PCC rule.

The situation of the manner correspondence is not have pre-configured PCC rule on the PCRF, and then PCRF can obtain the up PCC rule corresponding with described mobile terminal identification that prestores according to the mobile terminal identification of GW transmission from SPR.

In the manner, the CC-request message that GW sends to PCRF can be same as the prior art, all is that the sign of portable terminal sends to PCRF.Certainly, the CC-request message that GW sends to PCRF in the manner also can be identical with mode one, promptly can the AVP in the CC-Request message be expanded.CC-request message is carried the sign of portable terminal, can also carry the employed network segment address of a plurality of equipment that public described portable terminal divides into groups to insert by the cell of expansion; When not having pre-configured PCC rule on the PCRF, PCRF just handles according to the sign that CC-request message is carried portable terminal.

PCRF earlier obtains the up PCC rule of equipment the localized network with the sign corresponding mobile terminal agency of described portable terminal from SPR, more described up PCC rule is returned to GW.Perhaps in the manner, PCRF also can be simultaneously obtains up PCC rule of equipment and descending PCC rule the localized network with the sign corresponding mobile terminal agency of described portable terminal from SPR, and regular and descending PCC rule returns to GW with described up PCC again.Comprise the PCC IP filter in the PCC rule.

S303 changes out the TFT IP filter according to the up PCC IP filter in the described up PCC rule; And qos parameter and the described TFT IP filter in each described up PCC rule be issued to described portable terminal, so that portable terminal is set up corresponding relation for carrying and the TFT IP filter corresponding with described qos parameter.

After GW obtains the PCC rule of localized network by aforesaid dual mode, GW changes out the TFT IP filter according to the up PCC IP filter in the up PCC rule of obtaining, then can be by GW by GTP (GPRSTunnel Protocol with qos parameter in the described up PCC rule and described TFT IP filter, GPRS Tunnel Protocol) message is issued to portable terminal with the form of QoS file and TFT, specifically can be that GW is carrying described qos parameter and TFT IP filter for the cell by expansion in the response message of portable terminal distributing IP address.As in GPRS network, GW is GGSN (Gateway GPRS Supporting Node, GGSN), GGSN responds CreatePDP Context Response message and gives SGSN (Serving GPRS Supporting Node, the GPRS serving GPRS support node), and final notice comprises qos parameter and TFT IP filter information that portable terminal once activates the equipment that obtains behind the PDPContext to portable terminal in the message.

Because qos parameter and TFT IP filter all are arranged in the message at carrying, therefore, after portable terminal receives qos parameter and TFT IP filter, can set up the corresponding relation of carrying and TFT IP filter, be convenient to follow-up use.

Aforesaid TFT IP filter comprises mobile terminal side IP address of equipment attribute, for example can be Local Address and Subnet Mask, and type and length are identical with RemoteAddress and Subnet Mask in the prior art packet filtering.The concrete value of mobile terminal side IP address of equipment attribute is in the network segment of Framed-Subnet-IP-Address and Framed-Subnet-IP-Netmask or Framed-Subnet-IPv6-Prefix sign, and mobile terminal side IP address of equipment attribute is used for the IP matching addresses with the equipment that sends message.

Optionally, also comprise step S304, PCRF carries out related to the IP address of described portable terminal with described network segment address.

PCRF obtains network segment address two kinds of ways of realization: i) GW sends to PCRF with the network segment address of described localized network when sending mobile terminal identification, ii) SPR sends to PCRF with the network segment address corresponding with mobile terminal identification simultaneously when returning the PCC rule to PCRF.Described network segment address can carry by the cell of expansion.

If PCRF does not carry out related to the IP address of portable terminal with described network segment address, when the PCC rule under being summarised in mobile terminal identification changes, need the PCC rule of each equipment of portable terminal agency's localized network be refreshed, then can't find the PCC rule of each equipment of portable terminal agency's localized network to refresh.Therefore, preferred, PCRF carries out related to the IP address of described portable terminal and described network segment address, like this when refreshing the PCC rule according to mobile terminal identification, and can the Synchronous Processing PCC rule relevant with described network segment address.For example the charging of whole localized network may be summarised under the mobile terminal identification, if arrearage, then need the strategy in the relevant PCC rule of described network segment address all is revised as and forbid sending message to external network.

Further, GW can also carry out related with described network segment address to the IP address of described portable terminal.Wherein, GW can also carry out related with described network segment address to the IP address of described portable terminal, be when preventing that the described equipment of subsequent network side direction from sending downlink message, GW thinks according to the IP address of described equipment and causes professional use unusual by the not portable terminal of management and this downlink message is abandoned to one's name of this equipment.If certainly just can confirm according to the IP address of equipment that for GW the IP address that just need not to carry out described portable terminal is carried out related with described network segment address under the situation of the scope of to one's name managing.

In the present embodiment, the effect of portable terminal mainly is that session is set up and carrying is set up, so that each equipment in its agency's the localized network, uses session that portable terminal sets up and carrying and network side to carry out business exchange jointly.To the IP address of portable terminal and network segment address carry out related after, GW can put on an equal footing the IP address of described equipment and the IP address of portable terminal.And, when session is deleted, can thoroughly remove with the PCC rule of each equipment in the network segment address of the IP address correlation of the portable terminal of setting up this session, discharge the storage resources on the GW, guarantee the effective operation of GW.

Because GW is before the PCC rule of obtaining each equipment in the described localized network from PCRF, just obtained the network segment address of localized network, therefore, GW to the IP address of portable terminal and facility network sector address carry out related can be before sending CC-request to PCRF.

The uplink message that the equipment by the localized network that is arranged in described portable terminal agency that S305, GW mobile terminal receive transmit sends.

Described uplink message is transmitted by the carrying corresponding with described TFT IP filter after matching the TFT IP filter corresponding with the IP address of equipment in the described uplink message by portable terminal.

After the uplink message that portable terminal sends equipment was transmitted to GW, GW will carry out PCC to this uplink message according to the up PCC rule of this equipment correspondence, for example whether allow by, whether need the fields such as IP address in the message are revised and charging etc.

TFT IP filter in the embodiment of the invention has increased mobile terminal side IP address of equipment attribute, is used for and sends the IP matching addresses of the equipment of uplink message.When portable terminal is not acted on behalf of localized network and when initiating the equipment of uplink message, described mobile terminal side IP address of equipment attribute just is used for the IP matching addresses with portable terminal.

Portable terminal carries out the coupling of TFT IP filter to described uplink message, then by the carrying of storing on the portable terminal and the corresponding relation of TFT IP filter, obtain and the corresponding carrying of described TFT IP filter, and this uplink message is bundled in the described carrying is transmitted to GW.

Wherein, coupling be meant the field information (as each field of IP heading and TCP/UDP) of determining the uplink data messages that gets access to and the Business Stream information (the corresponding attribute in the IP filter as described) that writes down is identical respectively or each field value lay respectively at as described in the span of each attribute of TFT IP filter.

For example, the protocol type in the uplink message is 6 (being TCP), and source port number is 1000, and the destination slogan is 1200, and purpose IP address is 201.2.2.1.(the bracket front is the IP address field and the content of the Remote Address andSubnet Mask attribute in IP filter is for { 201.2.2.0[255.255.255.0] }, bracket inside is netmask), the content of Protocol Number attribute is 6 (expression TCP), the following of Local Port Range attribute is limited to 900, on be limited to 1100, the value of Remote Port Range attribute is 1200.Because purpose IP address 201.2.2.1 belongs to the represented network segment scope of Remote Address and SubnetMask attribute in the uplink message, source port number 1000 belongs to Local Port Range attribute bound scope, and other field in the uplink message is identical with other corresponding attribute value in the TFT IP filter, so this uplink message and this TFT IP filter mate.If uplink message and existing any one TFT IP filter all do not match, in order to guarantee professional normal use, portable terminal and GW can be tied to this uplink message on the default bearer.

The source IP address that is appreciated that the equipment that divides into groups to insert for the common moving terminal should be an address in Framed-Subnet-IP-Address and the Framed-Subnet-IP-Netmask or the Framed-Subnet-IPv6-Prefix sign network segment.

S306, GW match with described uplink message in the corresponding up PCC IP filter in IP address of equipment, according to the up PCC rule of described up PCC IP filter correspondence, described uplink message is carried out PCC.

After GW receives the described uplink message of portable terminal forwarding, mate by up PCC IP filter described uplink message and self storage, find corresponding up PCC rule, described uplink message is carried out policy control and charging, thereby realize PCC described equipment.

Optionally, present embodiment also comprises: the purpose IP address that receives the external network transmission is the downlink message of IP address of equipment in the described localized network, obtain with described downlink message in the descending PCC IP filter of IP matching addresses of equipment, according to the descending PCC rule of described descending PCC IP filter correspondence, described downlink message is carried out PCC.

Wherein, descending PCC rule can be obtained simultaneously with above-mentioned up PCC rule, also can use and the identical acquiring way of up PCC rule, specifically can be referring to step 302.

For the equipment that accurately the common moving terminal is divided into groups to insert carries out PCC, in the PCC IP filter of PCC rule, the source IP address attribute of up PCC IP filter and the purpose IP address properties of descending PCC IP filter can accurately match concrete IP address of equipment, as long as value is in the network segment of Framed-Subnet-IP-Address and Framed-Subnet-IP-Netmask or Framed-Subnet-IPv6-Prefix sign.
